What programming language does NS2 use?
NS is licensed for use under version 2 of the GNU (General Public License) and is popularly known as NS2. It is an object-oriented, discrete event-driven simulator written in C++ and Otcl/tcl.
What is TCL script in NS2?
A configuration file in NS2 is an OTCL file called “TCL Simulation script”. It also contains information about what we would like to simulate like node creation, also topology creation, setting up link etc. A TCL file is also an input configuration file for C++ file. To run the TCL file, use the command.
What is the purpose of NS2?
Network Simulator 2 (NS2) provides substantial support for simulation of different protocols over wired and wireless networks. It provides a highly modular platform for wired and wireless simulations supporting different network elements, protocols, traffic, and routing types [20].
What are the minimum requirements of NS2?
NS2: Combat minimum requirements
- Memory: 4 GB.
- Graphics Card: ATI Radeon HD 5850.
- CPU: AMD Phenom II X4 965.
- File Size: 12 GB.
- OS: 64-bit Win XP, Vista, Win 7, Win 8.
Why language is used in NS2?
OTcl is a language for creating a network so that you don’t have to recompile the codes every time you make changes to your simulation scenarios. It is also used to connect blocks (e.g., classifier, links, agent) within each NS2 components (e.g., node).
What is meant by NS2?
NS2 stands for Network Simulator Version 2. It is an open-source event-driven simulator designed specifically for research in computer communication networks.
What is NS2 and its specifications?
NS2 consists of two key languages: C++ and Object-oriented Tool Command Language (OTcl). While the C++ defines the internal mechanism (i.e., a backend) of the simulation objects, the OTcl sets up simulation by assembling and configuring the objects as well as scheduling discrete events.

Which is the programming language used in ns2?
In NS2 programming tutorial mainly deals two major programming paradigm i.e. C++ [programming language] and also Tool Command language [TCL- Scripting language]. To be more precise, NS2 is implemented in OTCL [Object oriented extension of TCL]. Let’s have a glance over the basics of TCL and OTCL.
What do you need to know about NS2?
Network simulator is a piece of software or hardware that predicates the performance of a network without a real network being there.NS2 is a vital simulation tool for networks. It supports a number of algorithms for routing and queuing. It can set up packet traffic related to internet and measure a variety of parameters.
Which is the object oriented extension of NS2?
To be more precise, NS2 is implemented in OTCL [Object oriented extension of TCL]. Let’s have a glance over the basics of TCL and OTCL. Used to write simulation script in NS2.
How to write a simulation script in ns2?
Used to write simulation script in NS2. “Set” command is used to create a variable and assign value to it. Here, we have declared a variable “a” with value 10. Value of any variable is used by using the symbol $. For ex, if we want to assign a value of a to another variable b, use the command:
